• Next to or directly above heaters or air conditioning vents, windows, wall vents etc. where air draughts can change the direction of airflow and cause rapid temperature fluctuations. • In very high or awkward areas (e.g. over stairwells) where it may be difficult to reach the Alarm (for testing, hushing etc.). • In or near very dusty or dirty areas as dust build-up on the optical smoke sensor can impair performance. It can block the insect screen mesh and prevent smoke from entering the sensor. Dust build up can also increase the response time of the heat sensor. • Locate the Alarm at least 1m from dimmer controlled lights and wiring as some dimmers can cause interference. • Locate the Alarm at least 1.5m and route wiring at least 1m away from fluorescent light fittings as electrical “noise” and/or flickering may affect the Alarm. Do not wire into the same circuit as fluorescent lights or dimmers. • In insect infested areas. Small insects getting into the optical smoke sensor can cause intermittent false alarms. Insects and contamination on the heat sensor can increase its response time. • In a damp or humid area. Do not locate Heat Alarms directly above a sink or cooker – Keep at least 1 m horizontal distance between these items and the Alarm.
